We can just place the set structures inside nir_block.
This reduces the number of ralloc calls by 6.7% when compiling Heaven
shaders with radeonsi+ACO using a release build (i.e. not including
nir_validate set allocations, which are also removed).

In the C23 standard unreachable() is now a predefined function-like
macro in <stddef.h>
See https://android.googlesource.com/platform/bionic/+/HEAD/docs/c23.md#is-now-a-predefined-function_like-macro-in
And this causes build errors when building for C23:
-----------------------------------------------------------------------
In file included from ../src/util/log.h:30,
from ../src/util/log.c:30:
../src/util/macros.h:123:9: warning: "unreachable" redefined
123 | #define unreachable(str) \
| ^~~~~~~~~~~
In file included from ../src/util/macros.h:31:
/usr/lib/gcc/x86_64-linux-gnu/14/include/stddef.h:456:9: note: this is the location of the previous definition
456 | #define unreachable() (__builtin_unreachable ())
| ^~~~~~~~~~~
-----------------------------------------------------------------------
So don't redefine it with the same name, but use the name UNREACHABLE()
to also signify it's a macro.
Using a different name also makes sense because the behavior of the
macro was extending the one of __builtin_unreachable() anyway, and it
also had a different signature, accepting one argument, compared to the
standard unreachable() with no arguments.
This change improves the chances of building mesa with the C23 standard,
which for instance is the default in recent AOSP versions.
All the instances of the macro, including the definition, were updated
with the following command line:
git grep -l '[^_]unreachable(' -- "src/**" | sort | uniq | \
while read file; \
do \
sed -e 's/\([^_]\)unreachable(/\1UNREACHABLE(/g' -i "$file"; \
done && \
sed -e 's/#undef unreachable/#undef UNREACHABLE/g' -i src/intel/isl/isl_aux_info.c

This is a cleanup.
Old gs LDS layout: [es outputs][gs outputs][scratch]
Old nogs LDS layout: [xfb/cull][scratch]
New gs LDS layout: [es outputs][scratch|gs outputs]
New nogs LDS layout: [scratch|xfb/cull]
The LDS scratch is moved to the beginning of the preceding buffer in LDS,
while the addresses in that LDS buffer are offset by the scratch size.
It effectively merges the LDS scratch with the preceding buffer in LDS.
Thanks to that, we no longer need the ngg_scratch ABI and the offset
in a user SGPR.
The lowering passes now return the LDS scratch size, which is used
by the drivers to determine the final LDS size.
The ngg_lds_layout SGPR is now unused without GS in RADV.

This hoists all the annoyance of figuring out the current pixel's input
attachment coordinates to the driver. The pass still deals with all the
annoyance of turning an image instruciton into a texture instruction but
it gives the driver more control over the position. For most drivers,
this will be something like ivec3(int(gl_FragCoord.xy), gl_Layer) or
similar, some drivers need something more nuanced. Turnip, for
instance, needs unscaled coordinates for some attachments and NVK
doesn't really want gl_Layer or gl_ViewIndex for the layer. It's better
to just have a new system value that drivers can make what they want.
